Genes affected
CLASP1 (HGNC:17088): (cytoplasmic linker associated protein 1) CLASPs, such as CLASP1, are nonmotor microtubule-associated proteins that interact with CLIPs (e.g., CLIP170; MIM 179838). CLASP1 is involved in the regulation of microtubule dynamics at the kinetochore and throughout the spindle (Maiato et al., 2003 [PubMed 12837247]).[supplied by OMIM, Mar 2008]
CLASP1-AS1 (HGNC:55328): (CLASP1 antisense RNA 1)
RNU4ATAC (HGNC:34016): (RNA, U4atac small nuclear) The small nuclear RNA (snRNA) encoded by this gene is part of the U12-dependent minor spliceosome complex. In addition to the encoded RNA, this ribonucleoprotein complex consists of U11, U12, U5, and U6atac snRNAs. The U12-dependent spliceosome acts on approximately 700 specific introns in the human genome. Defects in this gene are a cause of microcephalic osteodysplastic primordial dwarfism type 1 (MOPD).
